A personal digital assistant (PDA) is a multi-purpose mobile device which functions as a personal information manager. By 2007, PDAs have been mostly displaced by the widespread adoption of more highly capable smartphones, in particular those based on iOS and Android, and thus saw a rapid decline afterwards.
Palm OS was a mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It was provided with a suite of basic applications for personal information management. Later versions of the OS were extended to support smartphones. The software appeared on the company's line of Palm devices while several other licensees have manufactured devices powered by Palm OS.
A Pocket PC is a class of personal digital assistant (PDA) that runs the Windows Mobile or Windows Embedded Compact operating system that has some of the abilities of modern desktop PCs.

Some of these devices also had integrated phone and data capabilities, which were called Pocket PC Phone Edition. Windows "Smartphone" is another Windows CE based platform for non-touch flip phones or dumber phones.

Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage and allow for transmission of data, which can include voice and video transmissions. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats, and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.
A mobile device or handheld computer is a computer small enough to hold and operate in the hand. Mobile devices are typically battery-powered and possess a flat-panel display and one or more built-in input devices, such as a touchscreen or keypad.
